Can't build from Linux

[SeleDreams]

Hi, I've been trying to build the project on my arch linux machine, but everytime it seems to be missing the un4seen namespace. From what I know it's a C# wrapper around the BASS audio library. I thought it would be pulled from nuget automatically via the https://www.nuget.org/packages/Bass.Net package, but it doesn't seem to be the case... What's exactly expected to build it ? The build instructions in the wiki seem incomplete
